Dears,
I have a date value that has no milliseconds, and I want to concatenate System Timestamp milliseconds to that date.
I use GET_DATE_PART, but it didn't work.
What can I do regarding this?
Firstly generate the values in two ports. One for original date value and the other for sysdate value. Take a variable port and substring sysdate value until the date before the milliseconds and print just the milliseconds. Finally in the other port concatenate your original date value with milliseconds. If you can be able to post your codes, it would be more helpful to provide you relevant codes
Create a variable port in expression transformation with the below logic and pass it to the next level, like:
ADD_TO_DATE(i_DATE,'MS',TO_INTEGER(TO_CHAR(SYSTIMESTAMP(),'MS')))
Replace MS with NS if you want Nanoseconds.
Hope this helps!

I have to get the max payment date on an invoice and I am having trouble with the date format. I do not need the max in this formula as I am using the format in a reporting tool that is pulling the max from what it finds for me.
Using "to_char({datefield},'mm/dd/yyyy')" works for displaying that date the way we would like BUT when you use summary function MAX it does not pull the correct date because it is looking at a string and not a date (it will think 12/3/21 is larger than 3/2/22).
Another thing I have tried is trunc - "trunc({datefield})" which gives us the correct max date but it changes the formatting. For example if the date prior to the formula being applied is "8/12/21 12:00:00:000" the trunc formula will display it as 12-08-21 which is horribly wrong.
Long story short is I need a way to change a date/time to date with the format of 'mmmm/dd/yyyy' WITHOUT converting it to a string with something like to_char. Thank you!!!!
A DATE is a binary data type consisting of 7 bytes representing: century, year-of-century, month, day, hour, minute and second. It ALWAYS has all of those components and it is NEVER stored with any (human-readable) format.
What you are seeing when a date is displayed is the client application you are using to access the database making a decision to be helpful to you, the user, and display the binary DATE provided by the database in a human-readable format.
If you want to change how the DATE is displayed then you either need to:
Change the settings on the client application that controls how it formats dates when it displays them to you; or
Change the data-type so that it is no longer a DATE (which does not have a format) to a data type where the values of the date can be formatted (such as a string). You can do this using TO_CHAR.
If you want to find the maximum then do it BEFORE applying the formatting:
SELECT TO_CHAR(MAX({datefield}),'mm/dd/yyyy')
FROM your_table;
I'm building a dataflow where I want to filter rows based on the current time. I need to filter these based on the hour and minute.
I thought I could use a Date Time block. When I use that, the output value shows "today".
But when I bind the output of the Date Time block to the input on a Date Format block or my symbol, the value of the bound property is null.
I'm looking for a way to get the current date and time, preferably with a way to control how often the value is updated (once per minute would be enough for example).
Using a Script block works. The script to get the current timestamp with the precision of one minute as a string:
dateFormat(new DateTime(), "y-MM-dd HH:mm")
You can connect the output of the Script block to the input on a block that expects a "date", such as a Date Format block.
For the value to be updated, you must invoke the script block. To do this, a Stopwatch block can be used. In my case, I have it set to update every 10 seconds.
I have read many answers for combining date and time and nothing worked so far. I am working in Oracle SQL developer version 3.1.06 and I am trying to combine date and time stamps together. Date is in format dd-mmm-yy. And time is in the following 3 formats-
1. 0348A-- meaning 3:48 am
2. 03:48:00
3. 228 -- meaning minutes from midnight, calculated as (3*60)+48.
And for all these timestamps, I want a query that gets me to this format --
mm/dd/yyyy hh:mm:ss .
I can change the dates and times to string and attach them, but then when I work in powerpivot I am not able to change them to the required format. So, I want to do it in the query itself.
I have already tried something like this-
1. CAST(deptdt as DATETIME)+CAST(time as DATETIME)
2. CAST(depdt AS TIMESTAMP(0)) + (depdt - TIME '00:00:00' HOUR TO SECOND) AS DATETIME
Please help!!
For few columns from the source i.e .csv file, we are having values like 1:52:00, 14:45:00.
I am supposed to load to the Oracle table.
Which data type should I choose in Target as well as source?
Should i be doing any thing in the expression transformation?
Use SQLLDR to load the data into database with the format described as in the link
http://docs.oracle.com/cd/B19306_01/server.102/b14200/sql_elements004.htm
ie.'HH24:MI:SS'
Oracle does not support time-only values, it supports dates (with a time component).
You have a few options:
Store the value as a string, perhaps providing a leading zero for
the hour.
Store the value as the number of seconds (or minutes) past midnight.
Store the value as the time component of some arbitrarily defined date, for
example 0001-JAN-01 01:52:00 and 0001-Jan-01 14:45:00. Tell your report writers to ignore the date portion of the value.
Your source datatype will be string(8). Use LPAD to add leading zeroes.
I have last_update_date column defined as DATE field
I want to get time in milliseconds.
Currently I have:
TO_CHAR(last_update_date,'YYYY-DD-MM hh:mi:ss am')
But I want to get milliseconds as well.
I googled a bit and think DATE fields will not have milliseconds. only TIMESTAMP fields will.
Is there any way to get milliseconds? I do not have option to change data type for the field.
DATE fields on Oracle only store the data down to a second so there is no way to provide anything more precise than that. If you want more precision, you must use another type such as TIMESTAMP.
Here is a link to another SO question regarding Oracle date and time precision.
As RC says, the DATE type only supports a granularity down to the second.
If converting to TIMESTAMP is truly not an option then how about the addition of another numerical column that just holds the milliseconds?
This option would be more cumbersome to deal with than a TIMESTAMP column but it could be workable if converting the type is not possible.
In a similar situation where I couldn't change the fields in a table, (Couldn't afford to 'break' third party software,) but needed sub-second precision, I added a 1:1 supplemental table, and an after insert trigger on the original table to post the timestamp into the supplemental table.
If you only need to know the ORDER of records being added within the same second, you could do the same thing, only using a sequence as a data source for the supplemental field.
